  2. Column family - Wikipedia

    en.wikipedia.org/wiki/Column_family

    In analogy with relational databases, a column family is as a "table", each key-value pair being a "row". Each column is a tuple consisting of a column name, a value, and a timestamp. In a relational database table, this data would be grouped together within a table with other non-related data. Two types of column families exist:

  3. Line length - Wikipedia

    en.wikipedia.org/wiki/Line_length

    The matrix is used by locating the number closest to the previously calculated LCA on the left column of the matrix and then scanning across the columns the number of characters that one would like to set in the text line. Once the number is located, the top row of the selected column will indicate the ideal line length. [13]

  4. Buckling - Wikipedia

    en.wikipedia.org/wiki/Buckling

    A short steel column is one whose slenderness ratio does not exceed 50; an intermediate length steel column has a slenderness ratio ranging from about 50 to 200, and its behavior is dominated by the strength limit of the material, while a long steel column may be assumed to have a slenderness ratio greater than 200 and its behavior is dominated ...

  5. Johnson's parabolic formula - Wikipedia

    en.wikipedia.org/wiki/Johnson's_parabolic_formula

    The slenderness ratio is an indicator of the specimen's resistance to bending and buckling, due to its length and cross section. If the slenderness ratio is less than the critical slenderness ratio, the column is considered to be a short column. In these cases, the Johnson parabola is more applicable than the Euler formula.

  6. Euclidean vector - Wikipedia

    en.wikipedia.org/wiki/Euclidean_vector

    A unit vector is any vector with a length of one; normally unit vectors are used simply to indicate direction. A vector of arbitrary length can be divided by its length to create a unit vector. [14] This is known as normalizing a vector. A unit vector is often indicated with a hat as in â.

  7. PANDAS - Wikipedia

    en.wikipedia.org/wiki/PANDAS

    The children originally described by Susan Swedo et al. (1998) [17] usually had an abrupt onset of symptoms, including motor or vocal tics, obsessions, or compulsions. [18] [19] In addition to an obsessive–compulsive or tic disorder diagnosis, children may have other symptoms associated with exacerbations such as emotional lability, enuresis, anxiety, and deterioration in handwriting. [19]

    (For example: jeans label stating inner leg length of the jeans in centimetres or inches (not inner leg measurement of the intended wearer).) Ad hoc sizes: The label states a size number or code with no obvious relationship to any measurement. (For example: Size 12, XL.)
